I have to say, I was a bit stumped on this one for some reason, but I believe your answer is y^2.
Step-by-step explanation:
All four variables , (14, 15, y^2, & y^4) should all have a common denominator, but I only see similarities in y^2 with y^4 and 14 with 15, but the y's can be understood ones. Multiply your common variables and get y^2. Could someone check me in that though?

Answer: Population is 960 000
Step-by-step explanation: At the beginning time is zero and
population 60 000. We can count how many doubling happens.
Adding 274 hours four times, we get 274 , 548 , 822 and 1096.
So population doubles 4 times and we get numbers
120 000 240 000 480 000 and 960 000
